If you folks are still using remap_file_pages(), you may want to speak up in the thread on linux-kernel ...

Thank you for the notice! I've explained the PyPy situation, and it looks now like they're going to replace remap_file_pages() with an emulation based on mmap() and, I hope, take care of the issue that the mmap() solution is limited to 65536 by default (i.e., increase the default limit). This would be good enough for PyPy, where the calls to remap_file_pages() are themselves not highly performance-critical. A bientôt, Armin.
